PIC18 SD BMP Reader

This project uses Microchip's PIC18F2550 and Nokia 3310 LCD to read and display images from BMP files on the SD/MMC cards. Although the display itself is monochrome, it still supports 24-bpp (bits per pixel), 8-bpp, 4-bpp, and 1-bpp (monochrome) Bitmap files (*.BMP) with size of 84x48 pixels. It uses the Petit FAT File System Module by ChaN.
